The Dark Knight Rises already set an opening weekend record for a 2D film last week, but now it continues to break records, and some unexpected ones at that. Here’s the IMAX announcement:

IMAX Corporation and Warner Bros. Pictures today announced that The Dark Knight Rises generated strong second weekend global box office results of approximately $15 million in 479 IMAX® theatres worldwide over the weekend of July 29, bringing the film’s global IMAX cumulative box office to date to approximately $52 million.

“We’ve crossed the $50 million mark in the fastest time ever with The Dark Knight Rises, lifted, in part, by exceptional international box office,” said IMAX CEO Richard L. Gelfond. “Audiences are clearly seeking out and embracing the film the way it was meant to be seen – in IMAX. We are pleased by the second-weekend results and believe the film will continue to have the legs we anticipated.”
